[0051] The disclosure below provides many different embodiments or examples for realizing different structures of the present invention. In order to simplify the disclosure of the present invention, the components and settings of specific examples are described below. Of course, they are merely examples and are not intended to limit the present invention. In addition, the present invention may repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplicity and clarity and does not in itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the present invention provides examples of various specific processes and materials, but a person of ordinary skill in the art will appreciate the applicability of other processes and / or the use of other materials.

[0052] Hereinafter, an air conditioner 100 according to an embodiment of the present invention will be described with reference to the accompanying drawings.

[0053] like Figures 1-14As shown, the air conditioner 100 according to an embodiment of the present invention includes: a fan assembly 11, a fresh air component 2 and an electronic control box 3, the fan assembly 11 includes a cross-flow fan wheel 111 and a drive motor 112 for driving the cross-flow fan wheel 111 to rotate, and the axial direction of the cross-flow fan wheel 111 is the first direction F1; the fresh air component 2 is arranged at one end of the fan assembly 11 in the first direction F1, and the drive motor 112 is arranged at one end of the cross-flow fan wheel 111 in the first direction F1 close to the fresh air component 2; the electronic control box 3 includes a box body 31 and a circuit board 33 arranged in the box body 31, the box body 31 is arranged between the fan assembly 11 and the fresh air component 2, and is airtightly matched with at least part of the drive motor 112 and / or at least part of the fresh air component 2.

[0054] That is, the box body 31 defines an air-avoidance space, and at least a portion of the drive motor 112 and / or at least a portion of the fresh air component 2 occupies the air-avoidance space, allowing at least a portion of the drive motor 112 and / or at least a portion of the fresh air component 2 to intrude into the boundary area occupied by the box body 31 in the first direction F1. As a result, the stacking length L of the fan assembly 11, the electrical control box 3, and the fresh air component 2 along the first direction F1 is less than the sum of the lengths of the fan assembly 11, the electrical control box 3, and the fresh air component 2 along the first direction F1. Thus, the length of the air conditioner 100 along the first direction F1 can be reduced, facilitating a compact design of the air conditioner 100 for easier installation.

[0055] "The boundary area occupied by the box body 31 in the first direction F1" can be understood as: the area between the first plane and the second plane, wherein the first plane and the second plane are both perpendicular to the first direction F1, the first plane is the plane passing through the point on the box body 31 that is farthest from the fresh air component 2 in the first direction F1, and the second plane is the plane passing through the point on the box body 31 that is farthest from the fan assembly 11 in the first direction F1, so that the box body 31 as a whole can be completely located between the first plane and the second plane, or in other words, the first plane and the second plane are the two planes in the plane perpendicular to the first direction F1 that can accommodate the box body 31 and are the closest to each other.

[0056] The "stacked length L of the fan assembly 11, the electrical control box 3, and the fresh air component 2 along the first direction F1" refers to the maximum length, along the first direction F1, of the assembly formed by stacking the fan assembly 11, the electrical control box 3, and the fresh air component 2 along the first direction F1. The "sum of the lengths of the fan assembly 11, the electrical control box 3, and the fresh air component 2, along the first direction F1," refers to the sum of the maximum lengths of the fan assembly 11, the electrical control box 3, and the fresh air component 2, along the first direction F1.

[0057] First, if Figure 1-Figure 5As shown, the air conditioner 100 includes a fan assembly 11, a fresh air component 2, and an electrical control box 3. The fan assembly 11 includes a crossflow impeller 111 and a drive motor 112. The axial direction of the crossflow impeller 111 is a first direction F1. The drive motor 112 is disposed at one axial end of the crossflow impeller 111 and is power-connected to the crossflow impeller 111. The drive motor 112 can drive the crossflow impeller 111 to rotate, thereby allowing the air conditioner 100 to exhaust air outward.

[0058] Fresh air component 2 is used to introduce outdoor fresh air. Fresh air component 2 is disposed at one end of fan assembly 11 in the first direction F1, and drive motor 112 is disposed at one end of crossflow impeller 111 in the first direction F1, adjacent to fresh air component 2, such that fresh air component 2 and drive motor 112 are disposed relative to each other. Electrical control box 3 includes a housing 31 and a circuit board 33. Circuit board 33 is disposed within housing 31, which is disposed between fan assembly 11 and fresh air component 2. Circuit board 33 is electrically connected to fresh air component 2 and fan assembly 11, respectively, to provide power to fresh air component 2 and fan assembly 11.

[0059] The box body 31 can be arranged to fit within at least a portion of the drive motor 112; alternatively, the box body 31 can be arranged to fit within at least a portion of the fresh air component 2; or alternatively, the box body 31 can be arranged to fit within at least a portion of the drive motor 112 and at least a portion of the fresh air component 2. In this way, the stacking length L of the fan assembly 11, the electrical control box 3, and the fresh air component 2 along the first direction F1 can be made less than the sum of the lengths of the fan assembly 11, the electrical control box 3, and the fresh air component 2 along the first direction F1. This allows for an integrated design of the air conditioner 100, facilitates a compact design of the air conditioner 100, and facilitates installation of the air conditioner 100.

[0060] According to the air conditioner 100 of the embodiment of the present invention, by setting the box body 31, it can cooperate with at least part of the drive motor 112 and / or at least part of the fresh air component 2 to avoid air leakage, so that the stacking length L of the electric control box 3, the drive motor 112 and the fresh air component 2 along the first direction F1 can be smaller, thereby reducing the length of the air conditioner 100 along the first direction F1, which is conducive to realizing the miniaturized design of the air conditioner 100 and facilitating installation.

[0061] In some embodiments of the present invention, the air conditioner 100 is a wall mounted air conditioner, the first direction F1 is the left-right direction, the front end of the box body 31 is open for mounting the circuit board 33, the electric control box 3 includes a box cover 32 provided on the front side of the box body 31, and the portion of the drive motor 112 and / or the fresh air component 2 that fits in with the box body 31 to avoid air is located behind the box cover 32, that is, the box cover 32 blocks the front side of the portion of the drive motor 112 and / or the fresh air component 2 that fits in with the box body 31 to avoid air. It is worth noting that at least a portion of the box body 31 may or may not be present between the portion of the drive motor 112 and / or the fresh air component 2 that fits in with the box body 31 to avoid air and the box cover 32.

[0062] For example, refer to Figure 2-Figure 5 As shown, the air conditioner 100 can be configured as an on-hook air conditioner, with the first direction F1 being the left-right direction. The front end of the box body 31 is open to form an opening, and the circuit board 33 is arranged to match the opening so that the circuit board 33 can be installed into the box body 31 through the opening. The electric control box 3 also includes a box cover 32, which is arranged on the front side of the box body 31 to enclose the circuit board 33 within the box body 31.

[0063] Among them, the box cover 32 can be covered on the front side of the part of the driving motor 112 that cooperates with the box body 31 to avoid air; or, the box cover 32 can be covered on the front side of the part of the fresh air component 2 that cooperates with the box body 31 to avoid air; or, the box cover 32 can be covered on the front side of the part of the driving motor 112 that cooperates with the box body 31 to avoid air, and the part of the fresh air component 2 that cooperates with the box body 31 to avoid air.

[0064] It can be understood that by setting the first direction F1 as the left-right direction, the size of the air conditioner 100 along the left-right direction can be reduced to facilitate the installation of the air conditioner 100, and by providing the box cover 32, the drive motor 112 and / or at least part of the fresh air component 2 can be covered, so that the layout of the air conditioner 100 can be more regular, thereby improving the design rationality of the air conditioner 100.

[0065] In some embodiments of the present invention, Figure 3 and Figure 6 As shown, the box body 31 includes a first box portion 311 and a second box portion 312 connected to each other. The dimension of the first box portion 311 in the front-to-back direction is larger than the dimension of the second box portion 312 in the front-to-back direction. The second box portion 312 is arranged below the first box portion 311 and corresponds to the front end of the first box portion 311, so that an air-avoidance space 315 can be formed behind the second box portion 312. Among them, the drive motor 112 and / or the portion of the fresh air component 2 that cooperates with the box body 31 to avoid air is located behind the second box portion 312 and is arranged in the air-avoidance space 315.

[0066] Specifically, the part of the drive motor 112 that cooperates with the box body 31 to avoid air can be arranged to be located behind the second box part 312; or, the part of the fresh air component 2 that cooperates with the box body 31 to avoid air can be arranged to be located behind the second box part 312; or, the part of the drive motor 112 that cooperates with the box body 31 to avoid air can be arranged to be located behind the second box part 312, and the part of the fresh air component 2 that cooperates with the box body 31 to avoid air can be arranged to be located behind the second box part 312.

[0067] Through the above arrangement, the space of the air conditioner 100 along the front-to-back direction can be fully utilized, which is beneficial to reducing the space occupied by the electric control box 3 along the left-to-right direction and helping to reduce the overall size of the air conditioner 100.

[0068] In some embodiments of the present invention, Figure 3 As shown, part of the fresh air component 2 is located behind the second box portion 312 and below the first box portion 311. Through the above arrangement, the space of the air conditioner 100 in the up-down direction and the front-back direction can be fully utilized, which is conducive to improving the space utilization rate of the air conditioner 100 and realizing the miniaturization design of the air conditioner 100.

[0069] In some embodiments of the present invention, Figure 2-Figure 4 As shown, the fresh air component 2 includes a fresh air fan 21 and an air inlet duct component 22. The air inlet duct component 22 is arranged on the side of the fresh air fan 21 close to the electrical control box 3. At least part of the air inlet duct component 22 is located below the first box part 311 and behind the second box part 312.

[0070] Through the above setting, the fresh air fan 21 and the electronic control box 3 can maintain a certain distance to avoid mutual interference between the fresh air fan 21 and the electronic control box 3, and can reduce the heat accumulation of the air conditioner 100, lower the operating temperature of the air conditioner 100, and improve the service life of the air conditioner 100.

[0071] In some embodiments of the present invention, Figure 3 As shown, the width of the air inlet duct member 22 in the left-right direction can be set to gradually decrease from bottom to top, and a fresh air outlet 223 is opened at the rear side of the lower end of the air inlet duct member 22.

[0072] The above arrangement ensures the air intake of the air inlet duct member 22 and reduces the overall size of the air inlet duct member 22, thus saving installation space. Furthermore, by arranging the fresh air inlet 223 at the lower end of the air inlet duct member 22, the fresh air inlet 223 is more easily connected to the fresh air duct, thereby reducing the difficulty of assembling the air conditioner 100.

[0073] In some embodiments of the present invention, the upper end of the air inlet duct member 22 is formed with a first inclined surface 221 that gradually slopes downward from the fresh air component 2 to the fan assembly 11, and the lower end of the first box portion 311 is formed with a second inclined surface 3113 that matches the first inclined surface 221. There is a matching gap of 3mm-6mm between the first inclined surface 221 and the second inclined surface 3113 (refer to Figure 3 Dimension D1 shown).

[0074] For example, refer to Figure 3 As shown, a first inclined surface 221 can be formed at the upper end of the air inlet duct member 22, and the first inclined surface 221 is configured to gradually tilt downward from the direction of the fresh air component 2 to the fan assembly 11, and a second inclined surface 3113 can be formed at the lower end of the first box portion 311, and the second inclined surface 3113 is also configured to gradually tilt downward from the direction of the fresh air component 2 to the fan assembly 11, and the first inclined surface 221 and the second inclined surface 3113 have the same slope, so that the second inclined surface 3113 can be matched with the first inclined surface 221. There is a fitting gap between the first inclined surface 221 and the second inclined surface 3113, and the fitting gap ranges from 3mm to 6mm. For example, the fitting gap between the first inclined surface 221 and the second inclined surface 3113 can be 3mm, 4mm, 5mm, 6mm, etc., for example, 4.2mm.

[0075] Through the above arrangement, the air inlet duct member 22 and the first box portion 311 can be positioned more easily, and interference between the air inlet duct member 22 and the first box portion 311 due to installation errors can be prevented, thereby reducing the difficulty of assembling the air conditioner 100.

[0076] In some embodiments of the present invention, Figure 3 、 Figure 5 and Figure 7 As shown, the fresh air component 2 also includes a purification component 23. A pull-out opening 222 is formed on the front side of the air inlet duct component 22. The pull-out opening 222 and the second box portion 312 are arranged in sequence along the left-right direction. The pull-out opening 222 is matched with the purification component 23, and the purification component 23 is suitable for being installed in the air inlet duct component 22 through the pull-out opening 222. The fresh air opening 223 is located upstream of the purification component 23, and the inlet of the fresh air blower 21 is located downstream of the purification component 23. When the fresh air blower 21 is running, the fresh air flow can flow in from the fresh air opening 223 and flow through the purification component 23 to flow into the inlet of the fresh air blower 21. Exemplarily, the purification component 23 can be any one of a HEPA filter, a primary filter, and a sterilizing filter.

[0077] Through the above arrangement, the fresh air quality of the air conditioner 100 can be improved, and the practicality of the air conditioner 100 can be improved. In addition, during subsequent maintenance, the purification component 23 can be easily replaced through the pull-out opening 222, thereby improving user satisfaction.

[0078] In some embodiments of the present invention, the air inlet duct member 22 and the second box portion 312 have a matching gap of 6mm-12mm in the front-to-back direction (see Figure 8 The purification member 23 includes a handle portion 231, the handle portion 231 is provided on the side of the cover 32 away from the fan assembly 11, and the handle portion 231 and the second box portion 312 have a matching gap of 2mm-5mm in the left and right directions (refer to Figure 8 Dimension D3 shown).

[0079] For example, refer to Figure 3-Figure 5 as well as Figure 8 As shown, the air inlet duct member 22 and the second box portion 312 can be provided with a fitting gap along the front-to-back direction, and the fitting gap between the air inlet duct member 22 and the second box portion 312 in the front-to-back direction is set to a range of 6mm-12mm, such as 6mm, 7mm, 8mm, 9mm, 10mm, 11mm, 12mm, etc., for example, 9mm. Wherein, the purification member 23 includes a handle portion 231. The handle portion 231 is constructed in a shape that is easy to hold. The handle portion 231 is provided on the side of the box cover 32 away from the fan assembly 11. The handle portion 231 and the second box portion 312 have a fitting gap along the left-right direction. The fitting gap between the handle portion 231 and the second box portion 312 in the left-to-right direction is in the range of 2mm-5mm, such as 2mm, 3mm, 4mm, 5mm, etc., for example, 3.6mm.

[0080] Through the above-mentioned arrangement, interference between the air inlet duct member 22 and the second box portion 312 can be avoided, thereby improving the installation stability of the air conditioner 100, and interference between the purification member 23 and the box cover 32 during the disassembly and assembly process can be avoided, thereby ensuring the convenience of disassembly and assembly of the purification member 23 and improving the design rationality of the air conditioner 100.

[0081] In some embodiments of the present invention, referring to Figure 4 、 Figure 5 and Figure 8 As shown, the fresh air blower 21 includes a fan casing 211 and a centrifugal wind wheel 212. The fan casing 211 includes a volute portion 2111 and an air outlet portion 2112. The centrifugal wind wheel 212 is arranged in the volute portion 2111 and the axial direction of the centrifugal wind wheel 212 is left and right. The air outlet portion 2112 extends forward from the upper end of the volute portion 2111, and the front end of the air outlet portion 2112 forms an air outlet 21121.

[0082] Specifically, when the air conditioner 100 is in the fresh air mode, the centrifugal fan wheel 212 can rotate axially to suck the fresh air flow in the air inlet duct 22 into the volute portion 2111, and then, the centrifugal fan wheel 212 can send the fresh air flow into the air outlet portion 2112, so that the fresh air flow can be blown from the air outlet 21121 to the indoor space.

[0083] Through the above-mentioned setting, the flow path of the fresh air flow can be shortened, which is conducive to increasing the air volume of the fresh air flow, and the size of the fresh air fan 21 in the left and right directions can be reduced, and the size of the air conditioner 100 in the left and right directions can be reduced, thereby realizing the miniaturization design of the air conditioner 100.

[0084] In some embodiments of the present invention, Figure 2 、 Figure 4 and Figure 9 As shown, the air outlet portion 2112 can be arranged on the side of the first box portion 311 away from the fan assembly 11 in the left-right direction, and the air outlet portion 2112 and the first box portion 311 can be arranged to have a matching gap of 4mm-15mm in the left-right direction (refer to Figure 9 As shown in the dimension D4), the fitting clearance between the air outlet portion 2112 and the first box portion 311 in the left-right direction can be set to 4mm, 6mm, 8mm, 10mm, 12mm, 14mm, 15mm, etc., for example, 11.6mm.

[0085] Through the above-mentioned arrangement, the space occupied by the fresh air blower 21 in the up and down directions can be reduced, and the size of the air conditioner 100 in the up and down directions can be reduced. Moreover, by providing a fitting gap between the air outlet portion 2112 and the first box portion 311, interference between the air outlet portion 2112 and the first box portion 311 can be avoided, thereby reducing the difficulty of assembling the air conditioner 100.

[0086] In some embodiments of the present invention, Figure 8 As shown, at least a portion of the drive motor 112 can be located behind the second box portion 312, and the portion of the drive motor 112 located behind the second box portion 312 and the portion of the fresh air component 2 located behind the second box portion 312 are spaced apart in the left-right direction along the direction from the fan assembly 11 to the fresh air component 2. With the above arrangement, the space of the air conditioner 100 in the left-right direction can be more fully utilized, which helps to reduce the size of the air conditioner 100 in the left-right direction.

[0087] In some embodiments of the present invention, Figure 8 As shown, the driving motor 112 includes a motor cover 1121 and a motor body 1122. The axis of the motor body 1122 extends in the left and right directions, and the upper end of the motor body 1122 is lower than the lower end of the first box part 311. The motor cover 1121 is externally covered on the motor body 1122 and is arranged to avoid the first box part 311.

[0088] Through the above-mentioned arrangement, the motor body 1122 can extend to the bottom of the first box part 311, so as to make full use of the space of the air conditioner 100 in the upper and lower directions, which is conducive to reducing the overall size of the air conditioner 100, and can make the weight distribution of the air conditioner 100 more uniform, thereby improving the overall stability of the air conditioner 100.

[0089] In some embodiments of the present invention, Figure 8 、 Figure 10 and Figure 11 As shown, a matching gap of 0.5mm-2mm can be set between the motor cover 1121 and the first box part 311 (refer to Figure 11 The dimension D5 shown in the figure can be such that the clearance between the motor cover 1121 and the first box portion 311 can be set to 0.5 mm, 1 mm, 1.5 mm, 2 mm, etc., for example, 1 mm. This arrangement can prevent interference between the drive motor 112 and the first box portion 311, thereby reducing the difficulty of assembling the air conditioner 100.

[0090] In some embodiments of the present invention, Figure 8 As shown, the minimum gap between the motor cover 1121 and the fresh air component 2 (refer to Figure 8 The dimension D6) shown in the figure has a value range of 3 mm to 6 mm. For example, the minimum gap between the motor cover 1121 and the fresh air component 2 can be set to 3 mm, 4 mm, 5 mm, 6 mm, etc., for example, 4.9 mm. This arrangement can prevent interference between the drive motor 112 and the fresh air component 2, thereby improving the operating stability of the drive motor 112 and enhancing the reliability of the air conditioner 100.

[0091] In some embodiments of the present invention, Figure 12 As shown, the circuit board 33 includes a strong current board 331 and a weak current board 332. The strong current board 331 is arranged in the first box portion 311, and the weak current board 332 is arranged in the second box portion 312. Through the above arrangement, interference between the strong current board 331 and the weak current board 332 can be avoided, which is conducive to improving the reliability of the electric control box 3 and improving the operating stability of the air conditioner 100.

[0092] In some embodiments of the present invention, Figure 6 As shown, the first box portion 311 can be configured to be a flat box with a height smaller than the length and width, the length of the first box portion 311 being the front-to-back direction, the width of the first box portion 311 being the up-to-down direction, the height of the first box portion 311 being the left-to-right direction, and the length, width, and thickness of the strong current board 331 being consistent with the length, width, and height of the first box portion 311. Simultaneously, the second box portion 312 can be configured to be a flat box with a height smaller than the length and width, the height of the second box portion 312 being the front-to-back direction, the width of the second box portion 312 being the left-to-right direction, the length of the second box portion 312 being the up-to-down direction, and the length, width, and thickness of the weak current board 332 being consistent with the length, width, and height of the second box portion 312.

[0093] Through the above-mentioned arrangement, the air-avoidance space 315 formed behind the second box portion 312 can be made larger, so that at least part of the fresh air component 2 and at least part of the fan assembly 11 can be better placed in the air-avoidance space 315, which is beneficial to improving the space utilization of the air conditioner 100 and reducing the overall size of the air conditioner 100.

[0094] In some embodiments of the present invention, a side wall of the first box portion 311 close to the fan assembly 11 is a first box wall 3111, and a plurality of wire clamping openings 31111 are passed through the first box wall 3111, and the plurality of wire clamping openings 31111 are spaced apart in the up and down directions. The air conditioner 100 includes electric auxiliary heating, and the fan line 42 connected to the fan assembly 11 and the electric auxiliary heating line 41 connected to the electric auxiliary heating extend into the first box portion 311 through different wire clamping openings 31111 respectively to be connected to the high-voltage board 331 respectively.

[0095] For example, refer to Figure 13-14 As shown, a side wall of the box body 31 near the fan assembly 11 can be configured as a first box wall 3111. The first box wall 3111 is penetrated by multiple wire-locking openings 31111, which are spaced apart in the vertical direction. The air conditioner 100 includes electric auxiliary heating, which can be used to heat the conditioned air blown out by the fan assembly 11. The power line 4 includes an electric auxiliary heating line 41 and a fan line 42. The electric auxiliary heating line 41 is connected to the electric auxiliary heating line, and the fan assembly 11 is connected to the fan line 42.

[0096] Among them, the wire clamping opening 31111 is located at the end of the box body 31 close to the box cover 32 and is open toward the box cover 32. The fan line 42 and the electric auxiliary heating line 41 can be respectively clamped in different wire clamping openings 31111 from the open end to pass through the first box wall 3111, so that the fan line 42 and the electric auxiliary heating line 41 can extend into the first box body 31 to be connected to the high-voltage board 331, so that the electric control box 3 can supply power to the fan assembly 11 and the electric auxiliary heating through the high-voltage board 331.

[0097] It is understandable that by setting the fan line 42 and the electric auxiliary heating line 41 to be clamped in different clamping openings 31111, the risk of wire compression can be eliminated, the stability of the electric control box 3 can be improved, and the reliability of the air conditioner 100 can be improved.

[0098] In some embodiments of the present invention, the side wall of the first box portion 311 away from the fan assembly 11 is the second box wall 3112, and the left-right distance between the substrate 3311 of the high-voltage board 331 and the second box wall 3112 is greater than the left-right distance between the substrate 3311 of the high-voltage board 331 and the first box wall 3111. The side of the high-voltage board 331 facing the second box wall 3112 is provided with a first terminal connected to the fan line 42, and a second terminal connected to the electric auxiliary heating line 41.

[0099] For example, refer to Figure 13-14 As shown, the side wall of the first box part 311 away from the fan assembly 11 is set as the second box wall 3112, and the distance W2 between the substrate 3311 of the strong current plate 331 and the second box wall 31121 can be set to be larger than the distance W1 between the substrate 3311 of the strong current plate 331 and the first box wall 3111, so that the substrate 3311 can be set close to the first box wall 3111.

[0100] Among them, a first wiring terminal and a second wiring terminal can be provided on the side of the high-voltage board 331 facing the second box wall 3112, and the first wiring terminal and the second wiring terminal are arranged separately. The first wiring terminal is used to connect to the fan line 42 so that the high-voltage board 331 can supply power to the fan assembly 11, and the second wiring terminal is used to connect to the electric auxiliary heating line 41 so that the high-voltage board 331 can supply power to the electric auxiliary heating.

[0101] It can be understood that by setting the substrate 3311 of the high-voltage board 331 close to the first box wall 3111, the distance between the wire clamping port 31111 and the first terminal and the second terminal can be shortened, which is beneficial to shortening the length of the fan line 42 and the electric auxiliary heating line 41 and saving costs. By setting the first terminal and the second terminal on the side of the high-voltage board 331 facing the second box wall 3112, a larger operating space can be left for the installation of the fan line 42 and the electric auxiliary heating line 41, which is beneficial to reducing the difficulty of installation and improving the design rationality of the air conditioner 100.

[0102] In some embodiments of the present invention, referring to Figure 13-14 As shown, a wire hole 31121 can be provided on the second box wall 3112, and the wire hole 31121 connects the inside and outside of the first box part 311. The high-voltage electrical harness 5 including at least one of the power cord 51 and the indoor and outdoor unit connecting wire 52 is passed through the wire hole 31121 to be connected to the high-voltage board 331.

[0103] Exemplarily, a high-voltage electrical harness 5 can be provided including a power cord 51 and an indoor and outdoor unit connecting cord 52. Both the power cord 51 and the indoor and outdoor unit connecting cord 52 are passed through the wire hole 31121 and are electrically connected to the high-voltage board 331. An external power source can supply power to the high-voltage board 331 through the power cord 51, and the high-voltage board 331 can supply power to the air-conditioning outdoor unit through the indoor and outdoor unit connecting cord 52.

[0104] It can be understood that by arranging the high-voltage wire 4 on the first box wall 3111 and the high-voltage wire harness 5 on the second box wall 3112, the high-voltage wire 4 and the high-voltage wire harness 5 will not interfere with each other, and the line layout of the high-voltage board 331 can be made closer to the structure of the air conditioner 100, that is, the high-voltage wire 4 is close to the fan assembly 11 and the high-voltage wire harness 5 is close to the outside of the air conditioner 100, which is conducive to shortening the length of the line and improving the design rationality of the air conditioner 100.

[0105] In some embodiments of the present invention, the box body 31 includes a stop portion 313, which is arranged on a side of the first box portion 311 close to the fan assembly 11, and forms a wire accommodating space 314 between the stop portion 313 and the first box portion 311, and the wire accommodating space 314 is used to accommodate the high-voltage wire 4 passing through the wire clamping port 31111, the air conditioner 100 includes a ventilation and heat exchange component 1, the ventilation and heat exchange component 1 includes a fan assembly 11 and a heat exchanger 12, the fresh air component 2 and the electrical control box 3 are both located on the left side of the ventilation and heat exchange component 1 or on the right side of the ventilation and heat exchange component 1, the heat exchanger 12 is externally connected to a refrigerant pipeline 121, and the stop portion 313 blocks the wire accommodating space 314 and the refrigerant pipeline 121.

[0106] For example, refer to Figure 13-14 As shown, the box body 31 includes a stopper 313, which is provided on a side of the first box portion 311 near the fan assembly 11. At least a portion of the stopper 313 is spaced apart from the first box portion 311, so as to form a wire accommodating space 314 between the stopper 313 and the first box portion 311. The wire accommodating space 314 can be used to accommodate the power line 4 provided through the wire clamping opening 31111. It should be noted that the power line 4 includes the fan line 42 and the electric auxiliary heating line 41.

[0107] Air conditioner 100 includes a ventilation and heat exchange unit 1, which includes a fan assembly 11 and a heat exchanger 12. The fresh air unit 2 and the electrical control box 3 are located either on the left or right side of the ventilation and heat exchange unit 1, with the heat exchanger 12 located at the end of the fan assembly 11 near the electrical control box 3. A refrigerant line 121 is connected to the heat exchanger 12, located on the side of the heat exchanger 12 near the electrical control box 3. Heat exchanger 12 can exchange heat with conditioned air through refrigerant line 121, allowing the conditioned air to cool or heat the indoor space.

[0108] The stopper 313 can be blocked between the wire accommodating space 314 and the refrigerant pipe 121 . When condensed water forms on the outer wall of the refrigerant pipe 121 , the stopper 313 can prevent the condensed water from flowing toward the power line 4 .

[0109] It can be understood that the wire accommodating space 314 can be used to accommodate the excess part of the strong wire 4 to eliminate the wire length error of the strong wire 4, ensuring the precise installation of the strong wire 4, and the stopper 313 can prevent condensed water from flowing along the strong wire 4 and causing danger, thereby improving the safety of the air conditioner 100.

[0110] In some embodiments of the present invention, there are two wire-holding openings 31111, which are respectively located at the upper and lower ends of the first box wall 3111 and both penetrate in the left-right direction. The stop portion 313 includes two elastic buckles 3131, and the two elastic buckles 3131 are spaced apart in the up-down direction to form a wire-passing opening 3132 between the two elastic buckles 3131. The wire-passing opening 3132 is located between the two wire-holding openings 31111 in the up-down direction. The fan line 42 is suitable for entering the wire-holding space 314 through the wire-passing opening 3132 and passing upward into the wire-holding opening 31111 at the upper end. The electric auxiliary heating line 41 is suitable for entering the wire-holding space 314 through the wire-passing opening 3132 and passing downward into the wire-holding opening 31111 at the lower end.

[0111] For example, refer to Figure 13-14 As shown, two wire-binding openings 31111 can be provided, the two wire-binding openings 31111 being located at the upper and lower ends of the first box wall 3111, respectively, and both wire-binding openings 31111 passing through the first box wall 3111 in the left-right direction. The stopper 313 includes two elastic buckles 3131, which are spaced apart in the vertical direction to form a wire-passing opening 3132 between the two elastic buckles 3131. The wire-passing opening 3132 is connected to the wire-accommodating space 314, so that the fan wire 42 and the electric auxiliary heating wire 41 can enter the wire-accommodating space 314 through the wire-passing opening 3132. The wire-accommodating space 314 is connected to the wire-binding opening 31111, and the fan wire 42 and the electric auxiliary heating wire 41 entering the wire-accommodating space 314 can be respectively installed in the corresponding wire-binding openings 31111.

[0112] For example, in the specific installation process, the power cord 51 and the indoor and outdoor unit connecting wires 52 are first connected to the high-voltage board 331, and the fan wire 42 and the electric auxiliary heating wire 41 are pulled out to the front side of the box body 31; then, the high-voltage board 331 can be installed in the first box part 311 from front to back; then, the power cord 51 and the indoor and outdoor unit connecting wires 52 can be inserted into the wire threading hole 31121 from the right side of the box body 31; then, the fan wire 42 and the electric auxiliary heating wire 41 can be inserted into the wire accommodating space 314 through the wire passing port 3132 from the left side of the box body 31 and connected to the high-voltage board 331; finally, the fan wire 42 can be pulled upward along the wire accommodating space 314 to pass through the wire clamping port 31111 at the upper end, and the electric auxiliary heating wire 41 can be pulled downward along the wire accommodating space 314 to pass through the wire clamping port 31111 at the lower end, so that the line arrangement of the high-voltage board 331 can be realized.

[0113] Through the above-mentioned setting, the fan line 42 and the electric auxiliary heating line 41 entering the line space 314 can be kept parallel to the line clamping opening 31111, so that the fan line 42 and the electric auxiliary heating line 41 can be more easily clamped into the corresponding line clamping opening 31111, thereby reducing the assembly difficulty of the air conditioner 100, and avoiding the fan line 42 and the electric auxiliary heating line 41 from being intertwined, thereby improving the design rationality of the air conditioner 100.
